Kate, Wills ‘wipe’ Meghan, Harry

Prince William and his wife Kate's charity has officially removed all mention of Harry and Meghan from its title, marking the final stage in the Palace "split".

The Sun reports that documents published by Companies House overnight show the charity foundation, created by brothers Harry and William, is now known as The Royal Foundation of the Duke and Duchess of Cambridge - ditching mention of the Duke and Duchess of Sussex.

It follows Meghan and Harry's decision to move to Frogmore Cottage, Windsor, rather than remaining neighbours with their in-laws at Kensington Palace.

The move sparked feud rumours, although the Palace has strongly denied there is a rift among the siblings.

The Duke and Duchess of Sussex unveiled plans for their own charity, to be run from Buckingham Palace, in June.

William and Kate's charity paid £10 ($A18) to change its name, just 14 months after amending it to include Meghan - following the Sussexes' May 2018 royal wedding.

According to the documents, the name change was made official on August 8.
